After a first post on this topic (see here) I came across another document. The Central American Integration System (SICA) is the economic and political organization of Central American states. SICA has a Secretariat, SIECA which has its own website (here).
In 2011, SIECA and the Spanish Agency for International Development Cooperation published the third edition of the “Manual Centroamericano de Normas para el Diseño Geométrico de Carreteras” (Central American Manual on Standards for the Geometric Design of Highways).
The accompanying table is an update of the one published in my previous post, with some details added from the SIECA Manual. The comments in my previous post still stand, basically that:
- all these various multi-country standards could be merged into one standard, and
- all such standards (and perhaps national standards as well) should be given a common modular structure, so that engineers can compare the different recommendations on detailed topics such as side friction, minimum horizontal radius etc.
